Choosing the right Ball Valve involves more than confirming the pipe size. The valve structure, connection standard, pressure rating, body material, seat material, working temperature and operating medium must all be reviewed before the final model is selected.

This is especially important for valve companies and equipment manufacturers that plan to sell products under their own brands.

FVHOPES is currently communicating with a Turkish valve company that requires customized ball valves for its private-label product range. The customer has its own brand, but the final valve types, materials, sizes, pressure ratings and quantities are still under discussion. Therefore, the project remains at the inquiry and technical confirmation stage, and no final order has been confirmed.

This situation is common in OEM cooperation. A customer may know that it needs a flanged, threaded or three-piece ball valve, but reliable selection still depends on the actual operating conditions.

Start with the Application

Before choosing a valve, customers should first confirm:

• Working medium
• Maximum pressure
• Operating temperature
• Pipe size and connection standard
• Opening and closing frequency
• On-off or control function
• Manual or automated operation
• Maintenance requirements

Ball valves are commonly used for isolation and on-off control because they offer quarter-turn operation, a direct flow path and compact construction. However, different industrial systems require different valve structures.

FVHOPES ball valves are available for water, oil, steam and other compatible industrial media, subject to confirmation of material, pressure, temperature and sealing requirements.

Choose the Correct Ball Valve StructureTwo-Piece Flanged Ball Valve

A Two-Piece Flanged Ball Valve is suitable for industrial pipelines requiring a secure flanged connection.

According to the FVHOPES catalog, the standard model range is DN15–DN200 with PN16 nominal pressure. The valve includes an ISO 5211 mounting platform for actuator installation, as well as anti-static, stem anti-extrusion, pressure-balancing and fire-resistant structural features.

This structure is commonly considered for industrial pipelines and automated on-off systems.

Three-Piece Threaded Ball Valve

A Three-Piece Threaded Ball Valve is suitable for compact piping systems and applications requiring easier maintenance.

The center valve body can be removed for servicing while the pipeline connections remain in place. FVHOPES offers sizes from 1/2 inch to 4 inches, with NPT, BSPT and G thread options.

The catalog lists 1000 WOG and 2000 WOG pressure configurations, with oil, steam and water among the applicable media. The standard listed temperature range is -17°C to 120°C.

Three-Piece Flanged Ball Valve

A Three-Piece Flanged Ball Valve combines a maintainable three-piece structure with industrial flange connections.

The catalog includes pressure options from PN16 to PN40 and Class 150 to Class 300. Flange standards include HG/T 20592 and ASME B16.5.

This structure may be selected when customers need industrial flanged connections, higher pressure options and easier maintenance.

Clamp and Welded Ball Valves

A Three-Piece Clamp Ball Valve supports quick removal and is available with ISO 2852, DIN 32676 and 3A connection options.

A Butt-Weld Ball Valve provides a permanent welded connection, while a Socket-Weld Ball Valve offers a compact welded solution.

The connection type should be selected according to pipeline design, maintenance frequency, installation method and leakage control requirements.

Three-Way Ball Valve

A Three-Way Ball Valve is used to divert, combine or switch flow between different pipelines.

FVHOPES provides L-port and T-port configurations. The required flow path must be clearly confirmed before production because different ball channels provide different switching functions.

Tank Bottom and Sanitary Ball Valves

A Tank Bottom Ball Valve is designed for tank discharge systems. Its curved connection structure helps reduce material retention at the bottom of the tank.

A Sanitary Ball Valve is designed for material transfer in food, beverage, pharmaceutical and chemical processing systems. Clamp standards include ISO 2852, DIN 32676 and 3A.

These products should be selected according to cleaning, residue control and process connection requirements.

Confirm Body and Internal Materials

Material selection affects corrosion resistance, pressure capability and service life.

The FVHOPES catalog lists body material options including:

• WCB carbon steel
• CF8 stainless steel
• CF3M stainless steel

Ball and stem options include SS304, SS316 and SS316L, depending on the model.

Carbon steel may be suitable for general industrial applications, while stainless steel is often selected for improved corrosion resistance or cleaner fluid handling.

The final material should be confirmed according to:

• Medium composition
• Corrosion level
• Temperature
• Pressure
• Cleaning requirements
• Expected operating life

Material should not be selected only according to price.

Select the Correct Seat and Sealing Materials

The seat directly affects valve sealing, operating torque and temperature capability.

FVHOPES ball valve options include PTFE and reinforced PTFE seat materials. Selected structures also use FKM O-rings and graphite packing.

PTFE provides low operating torque and reliable sealing for many compatible media. Reinforced PTFE may offer improved mechanical strength for suitable operating conditions.

Seat selection should consider:

• Chemical compatibility
• Pressure and temperature
• Operation frequency
• On-off or control service
• Low-pressure or vacuum sealing

The catalog describes a seat structure designed to reduce operating torque while maintaining bidirectional sealing. However, customers should still provide complete operating data before the final seat configuration is confirmed.

Review Pressure and Temperature Together

Pressure and temperature should always be evaluated together.

A valve may have a nominal pressure rating, but the actual allowable operating condition also depends on the body material, seat material and connection type.

Examples from the FVHOPES catalog include:

• Two-piece flanged valve: DN15–DN200, PN16
• Three-piece threaded valve: 1/2–4 inches, 1000/2000 WOG
• Three-piece flanged valve: PN16–PN40 and Class 150–300
• Several three-piece models: listed working temperatures up to 220°C
• Threaded and socket-weld models: listed standard temperature range up to 120°C

These values are selection references. The final configuration should be checked against the actual maximum pressure and temperature of the customer’s system.

Check the Connection Standard

A valve with the correct nominal size may still be unsuitable if the connection standard is wrong.

FVHOPES connection options include:

• HG/T 20592 flange
• ASME B16.5 flange
• NPT, BSPT and G threads
• ISO 2852, DIN 32676 and 3A clamps
• Butt-weld connections
• Socket-weld connections

For the Turkish OEM inquiry, the required connection standards are still being discussed and must be confirmed before quotation and production.

Consider Safety and Structural Features

FVHOPES ball valve structures include several features for industrial applications.

Stem Anti-Extrusion Design helps prevent the valve stem from being pushed outward by internal pressure.

Anti-Static Design provides a conductive path between the ball, stem and valve body to discharge static electricity generated during operation.

Fire-Resistant Structure is available in selected valve designs. The required fire-safe standard and certification should be confirmed according to the project.

Pressure-Balancing Holes help balance pressure between the ball cavity and the medium under the intended operating condition.

Stem Sealing Structures use packing and O-ring arrangements to support reliable sealing and accommodate wear or temperature changes.

These features should be selected according to the actual service rather than added only as sales terms.

Confirm Automation Requirements

Many industrial ball valves are assembled with a Pneumatic Actuator or Electric Actuator.

FVHOPES ball valves use ISO 5211 mounting platforms across multiple models. However, actuator matching still requires confirmation of:

• Maximum valve torque
• ISO 5211 flange size
• Stem dimensions
• Available air pressure or voltage
• On-off or modulating control
• Fail-open or fail-close function
• Required feedback and accessories

For automated packages, the valve and actuator should be reviewed as one complete Valve Automation system.
